gender-free

(of people, not gradable) (Identifying themselves as) having no gender, as being neither male nor female nor any third gender.

2002, John Barth, Coming Soon!!!: A Narrative, page 294:

(of objects, options, etc) Socially acceptable for and available to any gender.

1988, The Connoisseur, volume 218, issues 912-915, page 108:

(of a society, gradable) Which does not define people in the basis of gender; in which gender is not present, or is insignificant or irrelevant to people's lives and choices.

The underlying argument is that if gender relations were altered at the level of social structure (ie, in the social institutions of the family, workplace, state policies, the courts, and media), a more gender-free world would eventually lead to gender-free parenting.
